Description
The problem is that the window transparency behaves randomly and not consistent when the mouse enters/leaves the main window area.
Partial code snippets shown as below. Please see framelesswindowtest_v1.zip
for the full test program.
setWindowFlags(Qt::FramelessWindowHint);
...
...
...
void DraftMainWindow::enterEvent(QEvent* event)
{
setWindowOpacity(1.0);
qDebug() << "Mouse enter event." << draftElapsedTimer.elapsed();
QWidget::enterEvent(event);
}
void DraftMainWindow::leaveEvent(QEvent* event)
{
setWindowOpacity(0.3);
qDebug() << "Mouse leave event." << draftElapsedTimer.elapsed();
QWidget::leaveEvent(event);
}
The issue cannot be reproducible with Qt 4.8.5 environment. Thus, it is likely a regression.
